Initially, such bowls were made of wood. Their shape varied depending on the region. For example, in Tver, bowls had an oval or cubic coaster. On one side they had a handle, and on the other, a groove for pouring. And in the region of the North Dvina, such vessels were round, had no handles and their upper edges were slightly bent outward. There were also vessels in the shape of swans, ducks or boats. Endovas were decorated with carved ornaments. Sometimes they had a lid, but more often they were open.

Metal endovas started to appear later. They were made of copper or silver by punching. At first, the blacksmiths forged a copper sheet to obtain a hemisphere of the desired shape. Then, using a special punching hammer, the workpiece was turned into a vessel. This method differed from minting because the crafters worked with cold rather than heated metal.

The ready bowl was cured on both sides, that is, covered with a thin layer of molten tin. After this treatment, the copper vessel did not oxidize and thus served longer. Also, the drinks it held did not acquire a metallic taste.
